Effect of ultrasonic irradiation on precipitation of lead oxalate from aqueous solution
- 75 Downloads
A precipitation reaction between a lead-nitrate solution and oxalic acid was carried out with and without ultrasound, and the effect of ultrasonic irradiation in solution was investigated. The oxalate precipitates were a mixture of Pb oxalate and an X-phase, which seems to be a lead salt containing C2O 4 2− NO 3 − , and OH−. It was found that irradiation with ultrasound during the precipitation reaction accelerated the formation of the X-phase.
